Background & Aim: There are different recommendations on how to use oral hygiene instruction in dental patients. The purpose of this study was to compare the amount of dental plaque formation following practical versus verbal oral hygiene instruction. Method & Material: This study was carried out on 36 dental students age 19-20 years old, who was matched and then randomly devided into 3 groups of experimental, positive control and negative control. Experimental group patients were instructed verbal and practical toothbrushing, in positive control group only oral hygiene was instructed verbally and in negative control group no oral hygiene instruction was done. Results: The changes in plaque index before instruction and 2 months after baseline in experimental group and positive control group were statistically significant. However no significant differences was found in negative control group. A comparison of changes in plaque indexes between experimental group and positive control group following 2 months showed statistically different results between these 2 groups, however the result was better in experimental group than control group. Conclusion: It can be concluded from the results of this study that practical methods of brushing is better than verbal oral hygiene instruction in removing the dental plaque.
